Events in Egypt put Sinai reefs at risk | Letters

In recent, soon to be published work, we show that the coral reefs of the Egyptian Sinai are the most valuable in the world, generating fine sand beaches, calm water and fabulous opportunities for world-class snorkelling and diving, all within a short flight from Europe.

The tragedy of recent events (Report, 11 November) is complex and manifold. Of course there is the loss of innocent life. And there is also the loss of critical foreign exchange to Egypt, and of employment and income locally.
